使用之前需重新编译示例中的extensions4QT工程

Comments

已经编译过了，用的生成后的extensions4QT.dll和lib文件，但还是不行。

---

vs左上角文件->添加现有项目->extensions4QT，右边栏解决方案管理器项目右键->项目依赖项，将其依赖于extensions4QT，再编译试试

---

示例代码是qtcreator版本，我转一个vs的工程，一起编译试试看行不行。

---

不是编译过？？应该会有vs工程啊？

---

没有，示例代码是qtcreator版本的，利用qtcreator版本编译出dll和lib文件后，在vs当中按照帮助文档跑示例代码链接不上。

---

依赖了Extensions4Qt工程也不行，应该是缺少lib文件吧，看到之前有人也问过这个问题，需要技术人员排查一下。

---

应该不会啊，我用的也是C组件，到目前运行良好，不缺少东西啊。

终于好了，将supermap-iobjectscpp-10.0.0-17726-74479-win-all\lib下对应的lib文件全部输入，OK了，可以排查一下究竟是缺哪个lib文件了。

---

确定了，需要输入SuFileParserd.lib文件，帮助文档可以更新一下了。

你好，我在编译vs2015+qt12

void QMapControl::Init()
{

    this->setMouseTracking(true);
    // 设置显示引擎类型
    UGGraphicsManager::SetCurGraphicsType(UGGraphics::GT_QT);
    // 初始化MapEditWnd
    m_pMapEditorWnd = new UGMapEditorWnd(); -------这个位置就中断了，
    m_pMapEditorWnd->Initialize();
    m_pMapEditorWnd->SetUserAction(UGDrawParamaters::uaPointModeSelect);
    //m_pMapEditorWnd->m_mapWnd.SetAfterMapDrawFunc(MapDrawnCallBack_QMap, (UGlong)this);
    m_pMapEditorWnd->SetTrackingFunc(TrackingCallBack, (UGlong)this);
    //m_pMapEditorWnd->SetTrackedFunc(TrackedCallBack, (UGlong)this);
}

请问你遇到过吗？卡在这里几天了

---

这边编译没有遇到过，可以具体描述一下问题？

---

你好就是我运行自带的例子，包含头文件执行

qMapControl = new QMapControl;然后就在

  m_pMapEditorWnd = new UGMapEditorWnd(); -------这个位置就中断了执行异常
